The Min. Record reference cited lists amethyst localities. The inclusion of Haddam refers to Dick Schooner's 1961 Mineralogy of Connecticut, which states the following: "The author has seen a three inch specimen of amethyst crystals, with albite, from a pegmatite in Haddam; this was exhibited at the Peabody Museum of Yale University." A check with the Peabody collection turned up YPM MIN 058341 described by staff as "mostly massive quartz (sorta smoky), some albite with muscovite, and what appears to be a secondary fracture or cavity (not enough there to know) filling of quartz that starts as a thin layer (~1mm) of white quartz against the massive quartz, that expands into a cluster of amethyst crystals. Nice color." Donated by J. F. Schairer. No specific locality recorded.
